Robustere Initialisierung & Routing-Refaktor

Browse Source 
- InitializeAsync in InitializeSafeAsync mit Fehlerbehandlung umbenannt, App-Start robuster gestaltet
- Asynchrone Initialisierung bei Window.Created
- Navigation vereinheitlicht: Routing.RegisterRoute statt Doppelslash, Navigation ohne Präfix
- Flyout-Menü in AppShell deaktiviert, ShellContent-Einträge entfernt
- Login/Register-ViewModels nutzen private Felder statt ObservableProperty
- SignalRService nutzt AccessToken aus AuthSessionService
- GameStateService: Automatischer Resync bei Verbindung, Fehlerhandling verbessert
- Navigation in ViewModels an neues Routing angepasst
- Aufräumarbeiten: Entfernte auskommentierte Messenger-Registrierungen, Initialisierung vereinheitlicht
